CORBA callbacks for JDK 1.5

Hi,

can anybody help me to find the example of callbacks functionality in CORBA for JDK 1.5?

The example (below) doesn't work by me.

http://java.sun.com/j2se/1.5.0/docs/guide/idl/jidlExample3.html#clientprop

There are no errors, but there is such sense that there is trouble in Listener ref = ListenerHelper.narrow(rootPOA.servant_to_reference(listener));

There are also many examples for JDK 1.3 or other, but i had no success with callbacks methods.

Is there any positive experience with JDK 1.5?

Thanks in advance!!!!!!
